RESUMO
BACKGROUND: Effects on anticancer therapy following the integration of palliative care and oncology are rarely investigated. Thus, its potential effect is unknown. AIM: To investigate the effects of the complex intervention PALLiON versus usual care on end-of-life anticancer therapy. DESIGN: Cluster-randomised controlled trial (RCT), registered at ClinicalTrials.gov (No. NCT03088202). The complex intervention consisted of a physician education program enhancing theoretical, clinical and communication skills, a patient-centred care pathway and patient symptom reporting prior to all consultations. Primary outcome was overall use, start and cessation of anticancer therapy in the last 3 months before death. Secondary outcomes were patient-reported outcomes. Mixed effects logistic regression models and Cox proportional hazard were used. SETTING: A total of 12 Norwegian hospitals (03/2017-02/2021). PARTICIPANTS: Patients ⩾18 years, advanced stage solid tumour, starting last line of anticancer therapy, estimated life expectancy ⩽12 months. RESULTS: A total of 616 (93%) patients were included (intervention: 309/control:307); 63% males, median age 69, 77% had gastrointestinal cancers. Median survival time from inclusion was 8 (IQR 3-14) and 7 months (IQR 3-12), and days between anticancer therapy start and death were 204 (90-378) and 168 (69-351) (intervention/control). Overall, 78 patients (13%) received anticancer therapy in the last month (intervention: 33 [11%]/control: 45 [15%]). No differences were found in patient-reported outcomes. CONCLUSION: We found no significant differences in the probability of receiving end-of-life anticancer therapy. The intervention did not have the desired effect. It was probably too general and too focussed on communication skills to exert a substantial influence on conventional clinical practice.
